Is it possible that the pot inside my TailTwister rotor has moved? My
antenna direction on my controller now shows 90 degrees off (to the West)

slipped in the rotator clamp or at the boom to mast clamp. I checked wiring
connections and all seems to be ok. Did the pot move 90 degrees? Anyone ever
see this before? I would appreciate any advice on this before I go through
the trouble of replacing the rotor with a spare. BTW, I am using a Green
Heron Engineering controller.

Unless they've changed the /ham series of rotators yse a wire wound resistor and a wiper fastened to the bell. It would be difficult for one of these to slip and still work at all. For them to be off either the bell has to be positioned wrong or the mast has slipped in the mount.
